The Korsteel Barrel Dee Snaffle is a very simple single jointed Dee Ring bit that is suitable for horses of all levels. The Barrel Dee applies pressure to the sides of the tongue, bars and lips while the Dee ring cheeks apply pressure at the sides of the face which can help teach younger horses (or reteach older horses) to turn. The fixed cheek pieces prevent the mouthpiece from pinching the horse's lips and sliding through his mouth.
